Sunrise-related logic

[cafri]

Hello,

(A newbie here)

I am quite new with OpenHAB2 - playing with it for a few days now.
Currently working for a few years with Vera and PLEG, and trying to define my logic with OpenHAB2 over Pi.

In my old controller, I have a lot of logic based on sunrise / sunset times.
For example:

• When sleeping with a window shutter open - close it 45 minutes before sunrise.
• Set a Light / dark hours switch - from 1 hour after sunrise to 1 hour before sunset.

How would you recommend implementing it with OpenHAB2?

• Create an Astro binding Thing with an offset for every required schedule?
• Create 1 Astro binding thing for the earliest before-sunrise / before-sunset required timing, and use timers (or expire binding) to trigger events based on other offsets? (for example: an astro binding with an offset of 1 hour before sunrise, and when it is triggered, a timer will used to trigger the 45 minutes before sunrise logic)
• Something else?

Thanks in advance.

[Deprecated] Design Pattern: Time Of Day

[Edit] Adde link to Time of Day State Machine For years now I’ve let this Design Pattern post get out of hand so I’m going to rein it in a bit now. It’s really expanded away from what it’s originally intended to be (i.e. a way to illustrate how to code a time based state machine) into a thread that is mostly about the example, Time of Day. It’s partially my fault for naming the thread “Time of Day”. But there are better alternatives for Time of Day in specific and time based state machines in g…
